STEM Challenge Week 4

It’s time for week 4 of our STEM at Home Challenges! Visit our blog every Thursday to see our latest STEM challenge and share your creations on Facebook using #CMMSSTEMChallenge or by emailing marketing@childrensmanor.com.

This week’s activity involves building a tin foil boat, seeing if it will float, and how many pennies it can hold before sinking. Please complete and share your results by Monday, April 27, 2020 so that we can share your boat on our Facebook pages.

Have you ever wondered why a ship can float? And better yet, how can a steel ship carry a heavy load without sinking? It has to do with the density, or the mass per volume, of the ship (and its cargo) compared to the density of water. In this science and engineering STEM activity, you will make little boats out of aluminum foil to explore how their size affects how much weight they carry and how this relates to the density of water.

Materials:
    • Tin foil 
    • 6 straws 
    • Scissors
    • Bucket/Bin/Bathtub filled with water
    • Pennies
Directions:
    1. Using your tin foil and straws, construct a boat that you think will float when placed in water and can hold pennies inside without sinking. You may use scissors to cut the tin foil and straws if you wish. 
    2. Time to test your boat! First, do the float test to see if your boat will float on its own. Second, do the penny test. See how many pennies you can place in your boat until it sinks.
    3. Take a picture of your with your boat and let marketing@childrensmanor.com know if you passed the float test and how many pennies you were able to place in your boat before it sank.

We hope you have fun with this week’s challenge! See who can make the best boat in your family for a little friendly competition.
